La Jolla Institute scientist Shane Crotty, Ph.D., a respected vaccine researcher and member of one of the nation's top AIDS vaccine consortiums, has pinpointed key cells that trigger a potent antibody response to HIV, the virus that causes AIDS. Here, he discusses his finding which will significantly advance efforts to develop the world's first antibody-based HIV/AIDS vaccine.
